Method Detail

addRra

public void addRra(String vRra)
            throws IndexOutOfBoundsException

Parameters:

vRra -

Throws:

IndexOutOfBoundsException - if the index given is outside the bounds of the collection

addRra

public void addRra(int index,
                   String vRra)
            throws IndexOutOfBoundsException

Parameters:

index -

vRra -

Throws:

IndexOutOfBoundsException - if the index given is outside the bounds of the collection

deleteStep

public void deleteStep()

enumerateRra

public Enumeration<String> enumerateRra()

Method enumerateRra.

Returns:

an Enumeration over all possible elements of this collection

equals

public boolean equals(Object obj)

Overrides the java.lang.Object.equals method.

Overrides:

equals in class Object

Parameters:

obj -

Returns:

true if the objects are equal.

getRra

public String getRra(int index)
              throws IndexOutOfBoundsException

Method getRra.

Parameters:

index -

Returns:

the value of the java.lang.String at the given index

Throws:

IndexOutOfBoundsException - if the index given is outside the bounds of the collection

getRra

public String[] getRra()

Method getRra.Returns the contents of the collection in an Array.

Note: Just in case the collection contents are changing in another thread, we pass a 0-length Array of the correct type into the API call. This way we know that the Array returned is of exactly the correct length.

Returns:

this collection as an Array

getRraCollection

public List<String> getRraCollection()

Method getRraCollection.Returns a reference to '_rraList'. No type checking is performed on any modifications to the Vector.

Returns:

a reference to the Vector backing this class

getRraCount

public int getRraCount()

Method getRraCount.

Returns:

the size of this collection

getStep

public int getStep()

Returns the value of field 'step'. The field 'step' has the following description: step size for the RRD

Returns:

the value of field 'Step'.

hasStep

public boolean hasStep()

Method hasStep.

Returns:

true if at least one Step has been added

hashCode

public int hashCode()

Overrides the java.lang.Object.hashCode method.

The following steps came from Effective Java Programming Language Guide by Joshua Bloch, Chapter 3

Overrides:

hashCode in class Object

Returns:

a hash code value for the object.

iterateRra

public Iterator<String> iterateRra()

Method iterateRra.

Returns:

an Iterator over all possible elements in this collection

removeAllRra

public void removeAllRra()

removeRra

public boolean removeRra(String vRra)

Method removeRra.

Parameters:

vRra -

Returns:

true if the object was removed from the collection.

removeRraAt

public String removeRraAt(int index)

Method removeRraAt.

Parameters:

index -

Returns:

the element removed from the collection

setRra

public void setRra(int index,
                   String vRra)
            throws IndexOutOfBoundsException

Parameters:

index -

vRra -

Throws:

IndexOutOfBoundsException - if the index given is outside the bounds of the collection

setRra

public void setRra(String[] vRraArray)

Parameters:

vRraArray -

setRra

public void setRra(List<String> vRraList)

Sets the value of '_rraList' by copying the given Vector. All elements will be checked for type safety.

Parameters:

vRraList - the Vector to copy.

setRraCollection

public void setRraCollection(List<String> rraList)

Deprecated.

Sets the value of '_rraList' by setting it to the given Vector. No type checking is performed.

Parameters:

rraList - the Vector to set.

setStep

public void setStep(int step)

Sets the value of field 'step'. The field 'step' has the following description: step size for the RRD

Parameters:

step - the value of field 'step'.
