NumericAttribute

public NumericAttribute(java.lang.String attribute,
                        int type,
                        boolean signed)

Constructor.

Parameters:

attribute - The actual string representation of the attribute as defined in the broadcast spec.

type - The type of number (decimal or integer)

signed - True if the number is signed, false if not signed

Throws:

java.lang.IllegalArgumentException - if type is unrecognized.

java.lang.NullPointerException - if attribute is null

Method Detail

equals

public boolean equals(java.lang.Object obj)

Tells if two attributes are equal.

Overrides:

equals in class Attribute

Returns:

true if obj is NumericAttribute, its getType() returns same type as this attribute and its name and sign are the same as the name and sign of of this attribute, respecptively. Otherwise false is returned. Comparison of the names is not case sensitive.

getType

public int getType()

Tells if the number is of type integer, fixed-point or floating-point

Returns:

returns the type of the number

isSigned

public boolean isSigned()

Tells if the data type is signed

Returns:

returns true if signed, false if unsigned
