Interface PrimitiveValue

All Known Implementing Classes:

BoolValue, ByteValue, DoubleValue, FloatValue, IntValue, LongValue, PrimitiveValueBase, ShortValue, StringValue

public interface PrimitiveValue

Classes implementing this interface are responsible for parsing, setting and getting the value of the different basic Java data types that occur in an event expression. Placeholders represent all literal values in event expressions and set values in prepared event expressions.

Method Summary

PrimitiveValueType	getType() Returns the type of primitive value this instance represents.
java.lang.Object	getValueObject() Returns a value object.
void	parse(java.lang.String value) Parse the string literal value into the specific data type.
void	parse(java.lang.String[] values) Parse the string literal values supplied in the array into the specific data type.
void	setBoolean(boolean x) Set a boolean value.
void	setByte(byte x) Set a byte value.
void	setDouble(double x) Set a double value.
void	setFloat(float x) Set a float value.
void	setInt(int x) Set an int value.
void	setLong(long x) Set a long value.
void	setShort(short x) Set a short value.
void	setString(java.lang.String x) Set a string value.
