Method Detail

displaySize

public int displaySize()

Specified by:

displaySize in class Type

getJDBCTypeCode

public int getJDBCTypeCode()

Description copied from class: Type

Returns the JDBC type number of type, if it exists, otherwise the HSQLDB / SQL type.

Specified by:

getJDBCTypeCode in class Type

getJDBCClass

public java.lang.Class getJDBCClass()

Specified by:

getJDBCClass in class Type

getJDBCClassName

public java.lang.String getJDBCClassName()

Description copied from class: Type

Returns the JDBC class name of type, if it exists, otherwise the HSQLDB class name.

Specified by:

getJDBCClassName in class Type

getNameString

public java.lang.String getNameString()

Description copied from class: Type

Returns the name of the type

Specified by:

getNameString in class Type

getDefinition

public java.lang.String getDefinition()

Description copied from class: Type

Returns the full definition of the type, including parameters

Specified by:

getDefinition in class Type

isBooleanType

public boolean isBooleanType()

Overrides:

isBooleanType in class Type

getAggregateType

public Type getAggregateType(Type other)

Description copied from class: Type

Common type used in comparison opertions. other must be comparable with this.

Specified by:

getAggregateType in class Type

getCombinedType

public Type getCombinedType(Session session,
                            Type other,
                            int operation)

Description copied from class: Type

Result type of combining values of two types in different opertions. other type is not allways comparable with this, but a operation should be valid without any explicit CAST

Specified by:

getCombinedType in class Type

compare

public int compare(Session session,
                   java.lang.Object a,
                   java.lang.Object b)

Specified by:

compare in class Type

convertToTypeLimits

public java.lang.Object convertToTypeLimits(SessionInterface session,
