Class FieldDefinition

java.lang.Object
  oracle.toplink.tools.schemaframework.FieldDefinition

All Implemented Interfaces:

java.io.Serializable, java.lang.Cloneable

public class FieldDefinition
extends java.lang.Object
implements java.io.Serializable, java.lang.Cloneable

Purpose: Define a database field definition for creation within a table. This differs from DatabaseField in that it is used only table creation not a runtime.

Responsibilities:

• Store the name, java type, size and sub-size. The sizes are optional and the name of the java class is used for the type.

Method Detail

clone

public java.lang.Object clone()

Overrides:

clone in class java.lang.Object

getAdditional

public java.lang.String getAdditional()

Return any additional information about this field to be given when the table is created.

getConstraint

public java.lang.String getConstraint()

Return any constraint of this field. i.e. "BETWEEN 0 AND 1000000".

getForeignKeyFieldName

public java.lang.String getForeignKeyFieldName()

getName

public java.lang.String getName()

Return the name of the field.

getSize

public int getSize()

Return the size of the field, this is only required for some field types.

getSubSize

public int getSubSize()

Return the sub-size of the field. This is used as the decimal precision for numeric values only.

getType

public java.lang.Class getType()

Return the type of the field. This should be set to a java class, such as String.class, Integer.class or Date.class.

getTypeName

public java.lang.String getTypeName()

Return the type name of the field. This is the generic database type name, which can be used instead of the Java class 'type'. This is translated to a particular database type based on platform.

getTypeDefinition

public java.lang.String getTypeDefinition()

Return the type definition of the field. This is database-specific complete type definition like "VARCHAR2(50) UNIQUE NOT NULL". If this is given, other additional type constraint fields(size, unique, null) are meaningless.

isIdentity

public boolean isIdentity()

Answer whether the receiver is an identity field. Identity fields are Sybase specific, they insure that on insert a unique sequencial value is store in the row.

isPrimaryKey

public boolean isPrimaryKey()

Answer whether the receiver is a primary key. If the table has a multipart primary key this should be set in each field.

isUnique

public boolean isUnique()

Answer whether the receiver is a unique constraint field.

setAdditional

public void setAdditional(java.lang.String string)

Set any additional information about this field to be given when the table is created.

setConstraint

public void setConstraint(java.lang.String string)

Set any constraint of this field. i.e. "BETWEEN 0 AND 1000000".

setForeignKeyFieldName

public void setForeignKeyFieldName(java.lang.String foreignKeyFieldName)

setIsIdentity

public void setIsIdentity(boolean value)

Set whether the receiver is an identity field. Identity fields are Sybase specific, they insure that on insert a unique sequencial value is store in the row.

setIsPrimaryKey

public void setIsPrimaryKey(boolean value)

Set whether the receiver is a primary key. If the table has a multipart primary key this should be set in each field.

setName

public void setName(java.lang.String name)

Set the name of the field.

setShouldAllowNull

public void setShouldAllowNull(boolean value)

Set whether the receiver should allow null values.

setSize

public void setSize(int size)

Set the size of the field, this is only required for some field types.

setSubSize

public void setSubSize(int subSize)

Set the sub-size of the field. This is used as the decimal precision for numeric values only.

setType

public void setType(java.lang.Class type)

Set the type of the field. This should be set to a java class, such as String.class, Integer.class or Date.class.

setTypeName

public void setTypeName(java.lang.String typeName)

Set the type name of the field. This is the generic database type name, which can be used instead of the Java class 'type'. This is translated to a particular database type based on platform.

setTypeDefinition

public void setTypeDefinition(java.lang.String typeDefinition)

Set the type definition of the field. This is database-specific complete type definition like "VARCHAR2(50) UNIQUE NOT NULL". If this is given, other additional type constraint fields(size, unique, null) are meaningless.

setUnique

public void setUnique(boolean value)

Set whether the receiver is a unique constraint field.

shouldAllowNull

public boolean shouldAllowNull()

Return whether the receiver should allow null values.

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
