public void setKeyCompression(java.lang.Integer keyCompression)

Sets the key compression.

1. null - NOCOMPRESS
2. 0 - COMPRESS
3. > 0 - COMPRESS integer

getKeyCompression

public java.lang.Integer getKeyCompression()

1. null - NOCOMPRESS
2. 0 - COMPRESS
3. > 0 - COMPRESS integer

setSystemGenerated

public void setSystemGenerated(java.lang.Boolean generated)

Sets the System Generated flag. This flag indicates if the index was generated to support a constraint.

getSystemGenerated

public java.lang.Boolean getSystemGenerated()

Gets the System Generated flag. This flag indicates if the index was generated to support a constraint.

setTable

public void setTable(Table table)

Sets the table on which this index acts.

Parameters:

table - the table to which this index refers

getTable

public Table getTable()

Retrieves the table on which this index is defined.

Returns:

the table to which this index refers

getParent

public DBObject getParent()

Description copied from interface: DBObject

Returns the parent of this object, if one exists. This does not return the Schema for a SchemaObject. Schema's are not considered part of the ownership parent tree.

Specified by:

getParent in interface ChildDBObject

Specified by:

getParent in interface DBObject

Overrides:

getParent in class AbstractSystemObject

setParent

public void setParent(DBObject par)

Description copied from interface: ChildDBObject

Sets the parent of this object.

Specified by:

setParent in interface ChildDBObject

getProperty

public java.lang.Object getProperty(java.lang.String key)

Description copied from interface: DynamicPropertySet

Retrieves the value associated with a property.

Specified by:

getProperty in interface DynamicPropertySet

Overrides:

getProperty in class AbstractSchemaObject

Parameters:

key - the property key for which a value is desired. exists.

Returns:

the value of the requested property, or a null value if the property does not exist or is not set.

setProperty

public void setProperty(java.lang.String key,
                        java.lang.Object value)

Description copied from interface: DynamicPropertySet

Sets the value for a property. Setting a value to null removes that property.

Specified by:

setProperty in interface DynamicPropertySet

Overrides:

setProperty in class AbstractSchemaObject

Parameters:

key - the property key to set

value - the value to set

getType

public java.lang.String getType()

Description copied from interface: DBObject

Returns the type of this object. Valid types include things like tables, views, synonyms, and columns.

Specified by:

getType in interface DBObject

Returns:

a string describing the type of object.

setColumnExpressions

public void setColumnExpressions(IndexObject[] colExprs)

Sets the column expressions referenced by this index.

Parameters:

colExprs - an array containing the column expressions referenced by this index

getColumnExpressions

public IndexObject[] getColumnExpressions()

Retrieves the column expressions referenced by this index.

Returns:

an array containing the column expressions referenced by this index

addColumnExpression

public void addColumnExpression(IndexObject colExpr)

Adds a column to the list of indexed columns.

Parameters:

Parameters:

colExpr - the column expression to remove.

findOwnedObject

public DBObject findOwnedObject(DBObjectID id)

Description copied from class: AbstractDBObject

Returns a child of this object that has the given ID. The child is located by comparing IDs, not by calling resolveID() which is quicker. The method does not recurse to look for children of children. This method is a candidate for adding to the DBObject interface.

Specified by:

getSchema in interface SchemaObject

Overrides:

getSchema in class AbstractSchemaObject

Returns:

schema the Schema containing this object

setSchema

public void setSchema(Schema s)

Sets the index's schema. The schema is only remembered against the index if it is different to the owning table's schema.

Specified by:

setSchema in interface SchemaObject

Overrides:

setSchema in class AbstractSchemaObject

Parameters:

s - the Schema containing this object

copyToImpl

protected void copyToImpl(AbstractDBObject copy,

Overrides:

copyToImpl in class AbstractSchemaObject

Parameters:

copy - the copy being created of this object

copyParent - if this object is being copied underneath a parent, this parameter is the copy of the parent of this object, which will therefore need to be the parent of the copy of this object.

idPolicy - the policy for copying the object's ID.
