Method Detail

isLT

public boolean isLT(Comparable object)

Tests whether this object is less than the specified one.

Parameters:

object - The object with which this object is compared.

Returns:

True if this object is less than the specified one.

See Also:

AbstractObject.isLT(Opus5.Comparable)

isLE

public boolean isLE(Comparable object)

Tests whether this object is less than or equal to the specified one.

Parameters:

object - The object with which this object is compared.

Returns:

True if this object is less than or equal to the specified one.

See Also:

AbstractObject.isLE(Opus5.Comparable)

isGT

public boolean isGT(Comparable object)

Tests whether this object is greater than the specified one.

Parameters:

object - The object with which this object is compared.

Returns:

True if this object is greater than the specified one.

See Also:

AbstractObject.isGT(Opus5.Comparable)

isGE

public boolean isGE(Comparable object)

Tests whether this object is greater than or equal to the specified one.

Parameters:

object - The object with which this object is compared.

Returns:

True if this object is greater than or equal to the specified one.

See Also:

AbstractObject.isGE(Opus5.Comparable)

isEQ

public boolean isEQ(Comparable object)

Tests whether this object is equal to the specified one.

Parameters:

object - The object with which this object is compared.

Returns:

True if this object is equal to the specified one.

See Also:

AbstractObject.isEQ(Opus5.Comparable)

isNE

public boolean isNE(Comparable object)

Tests whether this object is not equal to the specified one.

Parameters:

object - The object with which this object is compared.

Returns:

True if this object is not equal to the specified one.

See Also:

AbstractObject.isNE(Opus5.Comparable)

compare

public int compare(Comparable object)

Compares this object with the specified one.

Parameters:

object - The object with which this object is compared.

Returns:

An integer less than one if this object is less than the specified one; an integer greater than one if this object is greater than the specified one; and, zero if both objects are equal.
