Overrides:

copyFrom in class QueryTreeNode

Throws:

StandardException

getType

public DataTypeDescriptor getType()
                           throws StandardException

Get the resolved data type of this node. May be overridden by descendants.

Throws:

StandardException

isPrimitiveType

public boolean isPrimitiveType()
                        throws StandardException

Throws:

StandardException

getJavaTypeName

public String getJavaTypeName()
                       throws StandardException

Throws:

StandardException

setJavaTypeName

public void setJavaTypeName(String javaTypeName)

getPrimitiveTypeName

public String getPrimitiveTypeName()
                            throws StandardException

Throws:

StandardException

castToPrimitive

public void castToPrimitive(boolean booleanValue)

Toggles whether the code generator should add a cast to extract a primitive value from an object.

Parameters:

booleanValue - true if we want the code generator to add a cast false otherwise

mustCastToPrimitive

public boolean mustCastToPrimitive()

Reports whether the code generator should add a cast to extract a primitive value from an object.

Returns:

true if we want the code generator to add a cast false otherwise

getJSQLType

public JSQLType getJSQLType()
                     throws StandardException

Get the JSQLType that corresponds to this node. Could be a SQLTYPE, a Java primitive, or a Java class.

Returns:

the corresponding JSQLType

Throws:

StandardException

mapToTypeID

public TypeId mapToTypeID(JSQLType jsqlType)
                   throws StandardException

Parameters:

jsqlType - the universal type to map

Returns:

the corresponding compilation type id

Throws:
