org.eigenbase.oj
Class OJTypeFactoryImpl.OJScalarType

java.lang.Object
  org.eigenbase.reltype.RelDataTypeImpl
      org.eigenbase.oj.OJTypeFactoryImpl.OJScalarType

All Implemented Interfaces:

RelDataType, RelDataTypeFamily

Enclosing class:

OJTypeFactoryImpl

private class OJTypeFactoryImpl.OJScalarType
extends RelDataTypeImpl

Type based upon an OJClass.

Use this class only if the class is a 'pure' OJClass:

• If the OJClass is based upon a Java class, call OJTypeFactoryImpl.createJavaType(java.lang.Class) instead.
• If the OJClass is synthetic, call RelDataTypeFactoryImpl.createStructType(org.eigenbase.reltype.RelDataType[], java.lang.String[]) or RelDataTypeFactoryImpl.createJoinType(org.eigenbase.reltype.RelDataType[]) instead.

Method Detail

getComponentType

public RelDataType getComponentType()

Description copied from interface: RelDataType

Gets the component type if this type is a collection, otherwise null.

Specified by:

getComponentType in interface RelDataType

Overrides:

getComponentType in class RelDataTypeImpl

Returns:

canonical type descriptor for components

generateTypeString

protected void generateTypeString(StringBuilder sb,
                                  boolean withDetail)

Description copied from class: RelDataTypeImpl

Generates a string representation of this type.

Specified by:

generateTypeString in class RelDataTypeImpl

Parameters:

sb - StringBuffer into which to generate the string

withDetail - when true, all detail information needed to compute a unique digest (and return from getFullTypeString) should be included;
