Field Detail

metaData

protected java.util.Hashtable metaData

Stores the name-value properties for this variable for entries such as a description string, anomalies missing value codes, etc. that are interpreted by different "readers"

name

protected java.lang.String name

AbstractVariable

public AbstractVariable()

Method Detail

value

public java.lang.Object value(long i)

read

public int read(java.io.Reader reader)
         throws java.io.IOException

Read tokens from the input reader, in the sense of the class java.io.StreamTokenizer.

Following the sense of that class, tokens are either numbers or words (ends of line are ignored). The corresponding add() method is called using the numeric or string value field of the tokenizer.

add

public abstract void add(double value,
                         int which)

add

public abstract void add(java.lang.Object value,
                         int which)

metaData

public java.util.Hashtable metaData()

Accessor for metaData field

metaData

public java.util.Hashtable metaData(java.util.Hashtable value)

Accessor for setting metaData field

getName

public java.lang.String getName()

setName

public java.lang.String setName(java.lang.String val)

values

public VariableInt values(SelectorInt selector)

values

public abstract VariableInt values(int[] which)
