Constructor Detail

Text

public Text(TextType type)
     throws VisADException

construct a Text object with the missing value

Throws:

VisADException

Text

public Text(TextType type,
            String value)
     throws VisADException

construct a Text object

Throws:

VisADException

Text

public Text(String value)

construct a Text object with the generic TEXT type (TextType.Generic)

Method Detail

getValue

public String getValue()

isMissing

public boolean isMissing()

Returns:

flag indicating whether this Data has a missing value

binary

public Data binary(Data data,
                   int op,
                   int sampling_mode,
                   int error_mode)
            throws VisADException

Description copied from class: DataImpl

Pointwise binary operation between this and data. Applies to Reals, Tuples (recursively to components), and to Field ranges (Field domains implicitly resampled if necessary). Does not apply to Field domains or Sets (regarded as domains of Fields wthout ranges). Data.ADD is only op defined for Text, interpreted as concatenate. MathTypes of this and data must match, or one may match the range of the other if it is a FunctionType.

Specified by:

binary in interface Data

Overrides:

binary in class DataImpl

Parameters:

data - other Data operand for binary operation

op - may be Data.ADD, Data.SUBTRACT, etc; these include all binary operations defined for Java primitive data types

sampling_mode - may be Data.NEAREST_NEIGHBOR or Data.WEIGHTED_AVERAGE

error_mode - may be Data.INDEPENDENT, Data.DEPENDENT or Data.NO_ERRORS;

Returns:

result, which takes the MathType of this unless the default Units of that MathType conflict with Units of the result, in which case a generic MathType with appropriate Units is constructed

Throws:

VisADException - a VisAD error occurred

unary

public Data unary(int op,
                  int sampling_mode,
                  int error_mode)
           throws VisADException

Description copied from class: DataImpl

Pointwise unary operation applied to this. Applies to Reals, Tuples (recursively to components), and to Field ranges (Field domains implicitly resampled if necessary). Does not apply to Field domains, Sets (regarded as domains of Fields wthout ranges) or Text.

Specified by:

unary in interface Data

Overrides:

unary in class DataImpl

Parameters:

op - may be Data.ABS, Data.ACOS, etc; these include all unary operations defined for Java primitive data types

sampling_mode - may be Data.NEAREST_NEIGHBOR or Data.WEIGHTED_AVERAGE

error_mode - may be Data.INDEPENDENT, Data.DEPENDENT or Data.NO_ERRORS;

Returns:

result of operation, which takes the MathType of this unless the default Units of that MathType conflict with Units of the result, in which case a generic MathType with appropriate Units is constructed

Throws:

VisADException - a VisAD error occurred

computeRanges

public DataShadow computeRanges(ShadowType type,
                                DataShadow shadow)
                         throws VisADException

Description copied from interface: Data

Recursive version of computeRanges(), called down through Data object tree.

Parameters:

type - ShadowType generated for MathType of this

shadow - DataShadow instance whose contained double[][] array and animation sampling Set are modified according to RealType values in this, and used as return value

Returns:

DataShadow instance containing double[][] array of RealType ranges, and an animation sampling Set

Throws:

VisADException - a VisAD error occurred

toString

public String toString()

Overrides:

toString in class DataImpl

Returns:

a String representation of this

longString

public String longString(String pre)

Specified by:

longString in interface Data

Overrides:

longString in class DataImpl

Parameters:

pre - String added to start of each line

Returns:

a longer String than returned by toString(), indented by pre (a string of blanks)

compareTo

public int compareTo(Object object)

Compares this Text to another.

Parameters:

object - The other Text to compare against. It shall be a Text.

Returns:

A negative integer, zero, or a positive integer depending on whether this Text is considered less than, equal to, or greater than the other Text, respectively.

equals

public boolean equals(Object obj)

Indicates if this Text is semantically identical to an object.

Specified by:

equals in interface ScalarIface

Specified by:

equals in class Scalar

Parameters:

obj - The object.

Returns:

true if and only if this Text is semantically identical to the object.
