Method Detail

jjtAccept

public java.lang.Object jjtAccept(JavaParserVisitor visitor,
                                  java.lang.Object data)

Accept the visitor. *

Specified by:

jjtAccept in interface JavaNode

Overrides:

jjtAccept in class AbstractJavaNode

setIntLiteral

public void setIntLiteral()

isIntLiteral

public boolean isIntLiteral()

isLongLiteral

public boolean isLongLiteral()

Checks whether this literal is a long integer.

Returns:

true if this literal is a long

setFloatLiteral

public void setFloatLiteral()

isFloatLiteral

public boolean isFloatLiteral()

isDoubleLiteral

public boolean isDoubleLiteral()

Checks whether this literal describes a double.

Returns:

true if this literal is a double.

getValueAsInt

public int getValueAsInt()

getValueAsLong

public long getValueAsLong()

getValueAsFloat

public float getValueAsFloat()

getValueAsDouble

public double getValueAsDouble()

setCharLiteral

public void setCharLiteral()

isCharLiteral

public boolean isCharLiteral()

setStringLiteral

public void setStringLiteral()

isStringLiteral

public boolean isStringLiteral()

getEscapedStringLiteral

public java.lang.String getEscapedStringLiteral()

Tries to reconstruct the original string literal. If the original length is greater than the parsed String literal, then probably some unicode escape sequences have been used.

Returns:

isSingleCharacterStringLiteral

public boolean isSingleCharacterStringLiteral()

Returns true if this is a String literal with only one character. Handles octal and escape characters.

Returns:

true is this is a String literal with only one character
