Class ExecutableTextHolderTargetColumn

java.lang.Object
oracle.odi.interfaces.interactive.support.textholder.ExecutableTextHolderTargetColumn

All Implemented Interfaces:

IExecutableTextHolder

public class ExecutableTextHolderTargetColumn

extends java.lang.Object

implements IExecutableTextHolder

int	getNumberOfDataStores() Gets the number of source datastores.
SourceSet	getSourceSet() Returns the source set in which this TextHolder is located.
java.lang.String	getSql() Gets the String representation of the expression.
Expression	getSqlExpressionForPersistence() Gets the exrpession of this TextHolder as it will be persisted.
java.lang.Number	getSqlExpressionId() Basic getter of the repository ID of the text expression held by this text holder.
Expression	getSqlExpressionInMemory() Gets the expression of this TextHolder as it is in memory.
boolean	isAttachedSourceDataStoreSettable(int pDataStoreNumber) Returns whether it is possible to set this particular datastore number.
void	setAttachedSourceDataStore(int pDataStoreNumber, SourceDataStore pSourceDataStore) Sets one attached SourceDataStore.
void	setSourceSet(SourceSet pSourceSet) Sets the source set in which this TextHolder is located.
void	setSqlExpression(Expression pExpression) Sets the expression on the TextHolder.

Method Detail

getAttachedSourceDataStores

public SourceDataStore[] getAttachedSourceDataStores()

Gets the attached source datastores of this TextHolder.

Specified by:

getAttachedSourceDataStores in interface IExecutableTextHolder

Returns:

the attached datastores

getDataSet

public DataSet getDataSet()

Description copied from interface: IExecutableTextHolder

Basic getter.

Specified by:

getDataSet in interface IExecutableTextHolder

Returns:

the DataSet on which this TextHolder is located. May be null

getExecutionLocation

public OdiInterface.ExecutionLocation getExecutionLocation()

Description copied from interface: IExecutableTextHolder

Basic getter.

Specified by:

getExecutionLocation in interface IExecutableTextHolder

Returns:

the OdiInterface.ExecutionLocation of this textHolder

getNumberOfDataStores

public int getNumberOfDataStores()

Description copied from interface: IExecutableTextHolder

Gets the number of source datastores. This should be equal to getAttachedSourceDataStores().length.

Specified by:

getNumberOfDataStores in interface IExecutableTextHolder

Returns:

the number of attached datastores

getSqlExpressionForPersistence

public Expression getSqlExpressionForPersistence()

Description copied from interface: IExecutableTextHolder

Gets the exrpession of this TextHolder as it will be persisted.

Specified by:

getSqlExpressionForPersistence in interface IExecutableTextHolder

Returns:

the expression as it will be persisted

getSqlExpressionInMemory

public Expression getSqlExpressionInMemory()

Description copied from interface: IExecutableTextHolder

Gets the expression of this TextHolder as it is in memory. The big difference with the persisted one is that some cross references might not exist in the persisted version (journalized columns, language elements...).

Specified by:

getSqlExpressionInMemory in interface IExecutableTextHolder

Returns:

the expression as it is in memory

isAttachedSourceDataStoreSettable

public boolean isAttachedSourceDataStoreSettable(int pDataStoreNumber)

Description copied from interface: IExecutableTextHolder

Returns whether it is possible to set this particular datastore number.

Specified by:

isAttachedSourceDataStoreSettable in interface IExecutableTextHolder

Parameters:

pDataStoreNumber - the position of the datastore

Returns:

true if it is possible to call setAttachedSourceDataStore(pDataStoreNumber, aSourceDataStore)

setAttachedSourceDataStore

public void setAttachedSourceDataStore(int pDataStoreNumber,
                                       SourceDataStore pSourceDataStore)

Description copied from interface: IExecutableTextHolder

Sets one attached SourceDataStore. Please make sure that the pDataStoreNumber is settable by using isAttachedSourceDataStoreSettable().

Specified by:

setAttachedSourceDataStore in interface IExecutableTextHolder

Parameters:

pDataStoreNumber - the number of the attached SourceDataStore to be set

pSourceDataStore - the source datastore to attach

setSqlExpression

public void setSqlExpression(Expression pExpression)

Description copied from interface: IExecutableTextHolder

Sets the expression on the TextHolder.

Specified by:

setSqlExpression in interface IExecutableTextHolder

Parameters:

pExpression - the new expression for this TextHolder

getInterfaceSubComponent

public IInterfaceSubComponent getInterfaceSubComponent()

Description copied from interface: IExecutableTextHolder

Basic getter.

Specified by:

getInterfaceSubComponent in interface IExecutableTextHolder

Returns:

the underlying IInterfaceSubComponent

getSourceSet

public SourceSet getSourceSet()

Description copied from interface: IExecutableTextHolder

Returns the source set in which this TextHolder is located.

Specified by:

getSourceSet in interface IExecutableTextHolder

Returns:

The source set in which this textHolder is located. May be null.

See Also:

IExecutableTextHolder.setSourceSet(SourceSet)

setSourceSet

public void setSourceSet(SourceSet pSourceSet)

Description copied from interface: IExecutableTextHolder

Sets the source set in which this TextHolder is located.

Specified by:

setSourceSet in interface IExecutableTextHolder

Parameters:

pSourceSet - the source set to be set

See Also:

IExecutableTextHolder.getSourceSet()

getSql

public java.lang.String getSql()

Description copied from interface: IExecutableTextHolder

Gets the String representation of the expression.

Specified by:

getSql in interface IExecutableTextHolder

Returns:

the expression as a String

getSqlExpressionId

public java.lang.Number getSqlExpressionId()

Description copied from interface: IExecutableTextHolder

Basic getter of the repository ID of the text expression held by this text holder.

Specified by:

getSqlExpressionId in interface IExecutableTextHolder

Returns:

the ID of the expression held by this text holder
