Interface Consumer

public interface Consumer

A Consumer is something that will accept data (output), and do something with it. A consumer is like a SAX DocumentHandler or a PrintWriter, but more abstract. If a Sequence class impleemnts Consumer, then data "written" to the sequence will be inserted in the sequence.

Note: This interface is not quite final. For example it is probable we will add methods for comments, processing instructions, etc.

Method Detail

writeBoolean

void writeBoolean(boolean v)

writeFloat

void writeFloat(float v)

writeDouble

void writeDouble(double v)

writeInt

void writeInt(int v)

writeLong

void writeLong(long v)

startDocument

void startDocument()

endDocument

void endDocument()

startElement

void startElement(java.lang.Object type)

endElement

void endElement()

startAttribute

void startAttribute(java.lang.Object attrType)

Write a attribute for the current element. This is only allowed immediately after a startElement.

endAttribute

void endAttribute()

End of an attribute or end of an actual parameter. The former use matches a startAttribute; the latter may not, and can be used to separate parameters in a parameter list. This double duty suggsts the method should at least be re-named.

writeObject

void writeObject(java.lang.Object v)

ignoring

boolean ignoring()

True if consumer is ignoring rest of element. The producer can use this information to skip ahead.

write

void write(int ch)

write

void write(java.lang.String string)

write

void write(java.lang.CharSequence string,
           int start,
           int length)

write

void write(char[] buf,
           int start,
           int length)
