Method Detail

setDataType

public final void setDataType(short dataType)
Data type is a Writer.FLOAT.

Overrides:
setDataType in class Tag
Parameters:
dataType - The data type to set.

setDataType

setCount

public void setCount(int count)
Set the number of Writer.FLOAT contained in this tag.

Overrides:
setCount in class Tag
Parameters:
count - The number of Writer.FLOAT contained in the tag. If the number is bigger than the current count then it will add 0f Writer.FLOAT, else it will remove the Writer.FLOAT.

setExtraData

protected final void setExtraData(java.lang.Object obj)
Unused.

Overrides:
setExtraData in class Tag
Parameters:
obj - The extra data that the tag should contain.

getExtraData

getFloat

public final float getFloat(int index)
Get a Writer.FLOAT at the specified index.

Parameters:
index - The index to get the Writer.FLOAT.
Returns:
The Writer.FLOAT at the specified index.

setFloat

public final void setFloat(int index,
                           float val)
Set a Writer.FLOAT at the specified index.

Parameters:
index - The index to set the Writer.FLOAT.
val - The Writer.FLOAT to set at the specified index.

extraData

protected boolean extraData(boolean big)
This method figures out if any extra data is exists, this method can search the data type, extra data, value, and count. It is called whenever one of these types change.

Specified by:
extraData in class Tag
Parameters:
big - true if the tag is being written to a BigTIFF, false if otherwise.
Returns:
true if the tag contains extra data, false if otherwise.

setupForBigTIFF

protected void setupForBigTIFF(boolean set)
Setup the tag for writing in a BigTIFF.

Specified by:
setupForBigTIFF in class Tag
Parameters:
set - true if the tag should be preped for BigTIFF, false if otherwise.

writeData

public void writeData(Writer wr)
               throws java.io.IOException
The extra data writer, if any extra data exists then this method will be called and (through internal methods) a offset to the data will be used in place of the value parameter.

Specified by:
writeData in class Tag
Parameters:
wr - The writer used to write the extra data.
Throws:
java.io.IOException - If any IO exception occurs.

hasDefault

public boolean hasDefault()
Get if this Tag can have a default value, often defined by a parameter-less constructor.

Specified by:
hasDefault in class Tag
Returns:
true if the Tag has a default value, false if otherwise. Default is false.

isDefault

public boolean isDefault()
Get if this Tag's current value is the default value. This is ignored if Tag.hasDefault() returns false.

Specified by:
isDefault in class Tag
Returns:
true if the Tag's value is the default value, false if otherwise.
