Constructor Detail

XSBoolean

public XSBoolean(boolean x)

Initiates the new representation to the boolean supplied

Parameters:

x - Initialises this datatype to represent this boolean

XSBoolean

public XSBoolean()

Initiates to a default representation of false.

Method Detail

string_type

public java.lang.String string_type()

Retrieve the full type pathname of this datatype

Specified by:

string_type in class AnyType

Returns:

"xs:boolean", the full datatype pathname

type_name

public java.lang.String type_name()

Retrieve the datatype name

Specified by:

type_name in class CtrType

Returns:

"boolean", which is the datatype name.

string_value

public java.lang.String string_value()

Retrieve the String representation of the boolean value stored

Specified by:

string_value in class AnyType

Returns:

the String representation of the boolean value stored

value

public boolean value()

Retrieves the actual boolean value stored

Returns:

the actual boolean value stored

constructor

public ResultSequence constructor(ResultSequence arg)
                           throws DynamicError

Creates a new result sequence consisting of the retrievable boolean value in the supplied result sequence

Specified by:

constructor in class CtrType

Parameters:

arg - The result sequence from which to extract the boolean value.

Returns:

A new result sequence consisting of the boolean value supplied.

Throws:

DynamicError

eq

public boolean eq(AnyType arg)
           throws DynamicError

Comparison for equality between the supplied and this boolean representation. Returns true if both represent same boolean value, false otherwise

Specified by:

eq in interface CmpEq

Parameters:

arg - The XSBoolean representation of the boolean value to compare with.

Returns:

New XSBoolean representation of true/false result of the equality comparison

Throws:

DynamicError

gt

public boolean gt(AnyType arg)
           throws DynamicError

Comparison between the supplied and this boolean representation. Returns true if this XSBoolean represents true and that XSBoolean supplied represents false. Returns false otherwise

Specified by:

gt in interface CmpGt

Parameters:

arg - The XSBoolean representation of the boolean value to compare with.

Returns:

New XSBoolean representation of true/false result of the comparison

Throws:

DynamicError

lt

public boolean lt(AnyType arg)
           throws DynamicError

Comparison between the supplied and this boolean representation. Returns true if this XSBoolean represents false and that XSBoolean supplied represents true. Returns false otherwise

Specified by:

lt in interface CmpLt

Parameters:

arg - The XSBoolean representation of the boolean value to compare with.

Returns:

New XSBoolean representation of true/false result of the comparison

Throws:

DynamicError
