Method Detail

getType

public static DataType getType(java.lang.String name)

Find the DataType that matches this name.

Parameters:

name - find DataTYpe with this name.

Returns:

DataType or null if no match.

getType

public static DataType getType(java.lang.Class c)

Find the DataType that matches this class.

Parameters:

c - primitive or object class, eg float.class or Float.class

Returns:

DataType or null if no match.

toString

public java.lang.String toString()

The DataType name, eg "byte", "float", "String".

Overrides:

toString in class java.lang.Object

getSize
