Constructor Detail

SimpleConstant

public SimpleConstant(Location location)

Equivalent of the null literal.

SimpleConstant

public SimpleConstant(Location location,
                      byte value)

Equivalent of an literal, cast to byte.

SimpleConstant

public SimpleConstant(Location location,
                      short value)

Equivalent of an literal, cast to short.

SimpleConstant

public SimpleConstant(Location location,
                      int value)

Equivalent of an Java.IntegerLiteral with type int.

SimpleConstant

public SimpleConstant(Location location,
                      long value)

SimpleConstant

public SimpleConstant(Location location,
                      float value)

Equivalent of a Java.FloatingPointLiteral with type float.

Notice that this class supports the special values Float.NaN, Float.NEGATIVE_INFINITY and Float.POSITIVE_INFINITY, which can not be represented with a Java.FloatingPointLiteral.

                      double value)

Equivalent of a Java.FloatingPointLiteral with type double.

Notice that this class supports the special values Double.NaN, Double.NEGATIVE_INFINITY and Double.POSITIVE_INFINITY, which can not be represented with a Java.FloatingPointLiteral.

SimpleConstant

public SimpleConstant(Location location,
                      char value)

Equivalent of a Java.CharacterLiteral.

SimpleConstant

public SimpleConstant(Location location,
                      boolean value)

Equivalent of a Java.BooleanLiteral.

SimpleConstant

public SimpleConstant(Location location,
                      java.lang.String value)

Equivalent of a Java.StringLiteral, or, if value is null, the equivalent of a Java.NullLiteral.
