Field Detail

MIN_VALUE

protected java.math.BigDecimal MIN_VALUE

A lower bound for the value of this object, or null if none.

protected java.math.BigDecimal MAX_VALUE

An upper bound for the value of this object, or null if none.

value

protected T value

Constructor Detail

YangInt32

public YangInt32(java.lang.String s)
          throws YangException

Creates a YangInt32 object from a String.

Parameters:

s - The string.

Throws:

YangException - If value could not be parsed from s.

YangInt32

public YangInt32(java.lang.Number value)
          throws YangException

Creates a YangInt32 object from a Number. This may involve rounding or truncation.

Parameters:

value - The initial value of the new YangInt32 object.

Throws:

YangException - If value does not fit in 8 bits.

Method Detail

decode

protected java.lang.Integer decode(java.lang.String s)
                            throws java.lang.NumberFormatException

Returns a value of type T given a String. No implementation should use this.value - this method would be static if Java allowed for abstract static classes.

Parameters:

s - A string representation of a value of type T.

Returns:

A T value parsed from s.

Throws:

java.lang.NumberFormatException - If unable to parse a value of type T.

cloneShallow

protected YangInt32 cloneShallow()
                          throws YangException

Clones this object without cloning its value.

Returns:

A shallow clone of this object.

Throws:

YangException

setMinMax

protected void setMinMax(java.lang.Number minValue,
                         java.lang.Number maxValue)
                  throws YangException

Sets the MIN_VALUE and MAX_VALUE fields of this object.

Parameters:

minValue - value to set MIN_VALUE to.

maxValue - value to set MAX_VALUE to.

Throws:

YangException - If minValue is larger than maxValue.

valid

protected boolean valid(java.lang.Number n)

Parameters:

n - A number to check for validity.

Returns:

true if n is within this object's value domain; false otherwise.

check

public void check()
           throws YangException

Checks that the value of this object is not null and valid. Called in constructors and value setters. Subclasses that have state invariants in addition to those handled by the YangBaseInt.valid(java.lang.Number) method should override this method and throw a YangException if such an invariant has been violated.

Specified by:

check in interface YangType<T extends java.lang.Number>

Throws:

YangException - If the value of this object is null or invalid.

fromString

protected final T fromString(java.lang.String s)
                      throws YangException

Returns a value of type T given a String.

Note: This method is non-static since T is a non-static type.

Parameters:

s - A string representation of a value of type T.

Returns:

A T value parsed from s (not this.value!).

Throws:

YangException - If s does not contain a parsable T.

canEqual

public boolean canEqual(java.lang.Object obj)

Compares type of obj with this object to see if they can be equal.

If a subclass of this class overrides the equals method, this method should be overridden as well.

Parameters:

obj - Object to compare type with.

Returns:

true if obj type is compatible; false otherwise.

exact

protected void exact(java.lang.Number value)
              throws YangException

Checks that the value of this object equals another value.

Parameters:

value - The value to compare against.

Throws:

YangException - If comparison does not evaluate to true or if the value argument is not YangBaseInt.valid(java.lang.Number).

min

protected void min(java.lang.Number min)
            throws YangException

Checks that the value of this object is not smaller than the min-value.

Parameters:

min - The min-value to compare against.

Throws:

YangException - If value is smaller than min or min is invalid.

max

protected void max(java.lang.Number max)
            throws YangException

Checks that the value of this object is not larger than the max-value.

Parameters:

max - The max-value to compare against.

Throws:

YangException - If value is larger than max or max is invalid.

setValue

public void setValue(java.lang.String s)
              throws YangException

Description copied from interface: YangType

Sets the value of this object using a String.

Specified by:

setValue in interface YangType<T>

Parameters:

s - A string containing the new value to set.

Throws:

YangException - If an invariant was broken during assignment, or if value could not be parsed from s.

setValue

public void setValue(T value)
              throws YangException

Description copied from interface: YangType

Sets the value of this object using a value of type T.

Specified by:

setValue in interface YangType<T>

Parameters:

value - The new value to set.

Throws:

YangException - If an invariant was broken during assignment.

getValue

public T getValue()

Specified by:

getValue in interface YangType<T>

Returns:

The value of this object.

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

Returns:

The value of this object, as a String.

equals

public boolean equals(java.lang.Object obj)

Compares this object with another object for equality.

Overrides:

equals in class java.lang.Object

Parameters:

obj - The object to compare with.

Returns:

true if obj can be cast to a comparable type and the value of this object is equal to the value of obj; false otherwise.

hashCode

public int hashCode()

Overrides:

hashCode in class java.lang.Object

clone

public com.tailf.jnc.YangBaseType<T> clone()

Description copied from interface: YangType

Clones this object and its value.

Specified by:

clone in interface YangType<T>

Overrides:

clone in class java.lang.Object

Returns:

A deep clone of this object.
