Method Details

compareTo

int compareTo(T oScalar)

Specified by:

compareTo in interface Comparable<T extends PsyScalar>

psyLt

default PsyBoolean psyLt(T oScalar)

Returns a boolean object representing the result of “less” comparison of this object and a given object.

Parameters:

oScalar - an object with which this object is compared.

Returns:

a boolean value indicating if this object is less than given object.

psyLe

default PsyBoolean psyLe(T oScalar)

Returns a boolean object representing the result of “less or equal” comparison of this object and a given object.

Parameters:

oScalar - an object with which this object is compared.

Returns:

a boolean value indicating if this object is less than or equal to given object.

psyGt

default PsyBoolean psyGt(T oScalar)

Returns a boolean object representing the result of “greater” comparison of this object and a given object.

Parameters:

oScalar - an object with which this object is compared.

Returns:

a boolean result of comparison.

psyGe

default PsyBoolean psyGe(T oScalar)

Returns a boolean object representing the result of “greater or equal” comparison of this object and a given object.

Parameters:

oScalar - an object with which this object is compared.

Returns:

a boolean result of comparison.

psyCmp

default PsyInteger psyCmp(T oScalar)

Compares this object against given object and returns an integer indicating the result of the comparison. Returns negative value if this object is less than given one, zero if this object is equal to given one, and positive value if this object is greater than given one.

Parameters:

oScalar - an object with which this object is compared.

Returns:

a result of the comparison.

psyMin

default PsyScalar psyMin(T oScalar)

Returns the minimum of this scalar and given scalar.

Parameters:

oScalar - the given scalar.

Returns:

the minimum of this scalar and given scalar.

psyMax

default PsyScalar psyMax(T oScalar)

Returns the maximum of this scalar and given scalar.

Parameters:

oScalar - the given scalar.

Returns:

the maximum of this scalar and given scalar.
