Method Detail

getValue

Number getValue()

The value bits of this instance as an abstract number (Integer, Long, BigInteger). Always safe to call, independent of the result of isValueAnInt().

Returns:

the value bits of this instance as an abstract number

hasSameNumericalValue

boolean hasSameNumericalValue(Number compare)

Determines whether this instances value matches the one of the given number.

Parameters:

compare - the value to compare our value to

Returns:

true if the two numbers represent the same numerical value, false otherwise

isValueAnInt

boolean isValueAnInt()

Determines whether the value of this tag can be represented in a java int. Depending on the result of this method one of the getValueAsInt() or getValueBits() must be used to access the value.

Returns:

true if it is safe to call getValueAsInt(), false if getValueBits() must be used.

getValueAsInt

int getValueAsInt()

The value of this instance as a java int. May only be called if isValueAnInt() returned true.

Returns:

the value of this instance as a java int

Throws:

IllegalStateException - in case the value is too large for a java int

getValueLarge

Number getValueLarge()

The value bits of this instance as an abstract number (Long, BigInteger). May only be called if isValueAnInt() returned false.

Returns:

the value bits of this instance as an abstract number

Throws:

IllegalStateException - in case the value fits into a java int
