Method Detail

clearDataBufferData

public void clearDataBufferData()

Sets the vector in the DataBuffer to null This method should fire a PropertyChangeEvent

Specified by:

clearDataBufferData in interface GJDataVectorInterface<T>

setDataBuffer

public final void setDataBuffer(java.lang.Object buffer)

Description copied from interface: GJDataVectorInterface

Sets the DataBuffer used to store the data. The buffer will be copied by reference.

Specified by:

setDataBuffer in interface GJDataVectorInterface<T>

Parameters:

buffer - the object array or wrapper.

getDataBuffer

public final T getDataBuffer()

Description copied from interface: GJDataVectorInterface

Returns the DataBuffer.

Specified by:

getDataBuffer in interface GJDataVectorInterface<T>

Returns:

DataBuffer of type T

getEntry

public final java.lang.Object getEntry(int index)

Description copied from interface: GJDataVectorInterface

Returns a value from the DataBuffer

Specified by:

getEntry in interface GJDataVectorInterface<T>

Parameters:

index - of the required entry

Returns:

the value a a double

isCategorical

public boolean isCategorical()

Determines if this data set is categorical i.e. has that categories is non-null.

Specified by:

isCategorical in interface GJDataVectorInterface<T>

Returns:

true if Categories != null

setCategory

public void setCategory(double index,
                        java.lang.String val)

Associates a Category containing {code String} s with the specified double value.

Specified by:

setCategory in interface GJDataVectorInterface<T>

Parameters:

index -

val -

getCategories

public java.util.LinkedHashMap<java.lang.Double,Category> getCategories()

Returns the LinkedHasMap of category settings. See GJAbstractDataVector#categories categories in GJAbstractDataVector.

Specified by:

getCategories in interface GJDataVectorInterface<T>

Returns:

a LinkedHashMap

getCategory

public Category getCategory(double val)

Description copied from interface: GJDataVectorInterface

Returns the category associated with the specified double value.

Specified by:

getCategory in interface GJDataVectorInterface<T>

Returns:

a Category

setCategories

public void setCategories(java.util.LinkedHashMap<java.lang.Double,Category> cat)

Sets the LinkedHashMap containing the categories.

Specified by:

setCategories in interface GJDataVectorInterface<T>

Parameters:

cat - a LinkedHashMap map.

setCategories

public void setCategories(java.lang.String... cat)

getBufferClass

public final java.lang.Class getBufferClass()

Specified by:

getBufferClass in interface GJDataVectorInterface<T>

Returns:

the class of the DataBuffer

setDataBufferData

public void setDataBufferData(java.util.Map m)

Sets the vector in the DataBuffer to a series incrementing by 1 for each element. m must be a Map with a single key, which determines the start value of the series while the value corresponding to the key represents the upper limit of the series. TODO: Should this be removed?? This method should fire a PropertyChangeEvent when the buffer data are changed

Specified by:

setDataBufferData in interface GJDataVectorInterface<T>

Parameters:

m - a Map of size equal to 1.

getName

public java.lang.String getName()

Specified by:

getName in interface GJDataVectorInterface<T>

setName

public void setName(java.lang.String s)

Specified by:

setName in interface GJDataVectorInterface<T>

propertyChange

public void propertyChange(java.beans.PropertyChangeEvent pce)

Specified by:

propertyChange in interface java.beans.PropertyChangeListener
