Class DataType

java.lang.Object
  org.prorefactor.treeparser.DataType

All Implemented Interfaces:

Xferable

public class DataType
extends java.lang.Object
implements Xferable

One static instance of DataType is created for each data type in the 4GL. You can access each of those through this class's public static final variables. This class was created just so that we could look up, and store, an object instead of a String or int to represent data type. For example, we'll be adding datatype support into Field and schemaLoad next.

Only to be used for persistence/serialization.

Method Detail

getDataType

public static DataType getDataType(int tokenType)

Get the DataType object for an integer token type. This can return null - when you use this function, adding a check with assert or throw might be appropriate.

getDataType

public static DataType getDataType(java.lang.String progressCapsName)

Get the DataType object for a String "progress data type name", ex: "COM-HANDLE". Requires all caps characters, not abbreviated. This can return null - when you use this function, adding a check with assert or throw might be appropriate.

getProgressName

public java.lang.String getProgressName()

The progress name for the data type is all caps, ex: "COM-HANDLE"

getTokenType

public int getTokenType()

Returns the Proparse integer token type, ex: TokenTypes.COMHANDLE

toString

public java.lang.String toString()

Same as getProgressName.

Overrides:

toString in class java.lang.Object
