Class JrpcgenConst

java.lang.Object
  org.acplt.oncrpc.apps.jrpcgen.JrpcgenConst

public class JrpcgenConst
extends java.lang.Object

The JrpcgenConst class represents a single constant defined in an rpcgen "x"-file.

Field Summary

boolean	dontTraverseAnyMore Flag indicating whether this constant and its dependencies should be traversed any more.
java.lang.String	enclosure Specifies the enclosure (scope) within the identifier must be addressed for a constant defined by an enumumeration.
java.lang.String	identifier Constant identifier.
java.lang.String	value Contains value (or identifier refering to another constant) of constant.

Constructor Summary

JrpcgenConst(java.lang.String identifier, java.lang.String value)
Constructs a JrpcgenConst and sets the identifier and the associated value.

JrpcgenConst(java.lang.String identifier, java.lang.String value, java.lang.String enclosure)
Constructs a JrpcgenConst and sets the identifier and the associated value of an enumeration etc.

Method Summary

void	dump() Dumps the constant as well as its value to System.out.
java.lang.String	getDependencyIdentifier() Returns the identifier this constant depends on or null, if no dependency exists.
java.lang.String	resolveValue() Returns value as integer literal (and thus resolving identifiers recursively, if necessary).

Field Detail

identifier

public java.lang.String identifier

Constant identifier.

value

public java.lang.String value

Contains value (or identifier refering to another constant) of constant.

enclosure

public java.lang.String enclosure

Specifies the enclosure (scope) within the identifier must be addressed for a constant defined by an enumumeration.

dontTraverseAnyMore

public boolean dontTraverseAnyMore

Flag indicating whether this constant and its dependencies should be traversed any more.

Constructor Detail

JrpcgenConst

public JrpcgenConst(java.lang.String identifier,
                    java.lang.String value)

Constructs a JrpcgenConst and sets the identifier and the associated value.

Parameters:

identifier - Constant identifier to define.

value - Value assigned to constant.

JrpcgenConst

public JrpcgenConst(java.lang.String identifier,
                    java.lang.String value,
                    java.lang.String enclosure)

Constructs a JrpcgenConst and sets the identifier and the associated value of an enumeration etc.

Parameters:

identifier - Constant identifier to define.

value - Value assigned to constant.

enclosure - Name of enclosing enumeration, etc.

Method Detail

resolveValue

public java.lang.String resolveValue()

Returns value as integer literal (and thus resolving identifiers recursively, if necessary). This is only possible for simple subsitutions, that is A is defined as B, B as C, and C as 42, thus A is eventually defined as 42.

This simple kind of resolving is necessary when defining a particular version of an ONC/RPC protocol. We need to be able to resolve the version to an integer literal because we need to append the version number to any remote procedure defined to avoid identifier clashes if the same remote procedure is defined for several versions.

Returns:

integer literal as String or null, if the identifier could not be resolved to an integer literal.

getDependencyIdentifier

public java.lang.String getDependencyIdentifier()

Returns the identifier this constant depends on or null, if no dependency exists.

Returns:

dependency identifier or null.

dump

public void dump()

Dumps the constant as well as its value to System.out.
