Method Detail

addJsonValue

public abstract void addJsonValue(String name,
                                  Object value)

Add a dynamic property value that the json parser encounters. Dynamic property values are not predefined and are catch-all in nature.

Parameters:

name - name

value - value

getJsonValues

public abstract Map<String,Object> getJsonValues()

Returns the dynamic property values (the non-predefined values)

Returns:

map

getNativeSize

public abstract int getNativeSize()

Returns the total number of pre-declared properties available including properties of the parent event type if any

Returns:

size

getNativeEntry

public abstract Map.Entry<String,Object> getNativeEntry(int num)

Returns the name-value pre-declared property including properties of the parent event type if any

Parameters:

num - index number of the property

Returns:

entry

Throws:

NoSuchElementException - for invalid index

getNativeKey

public abstract String getNativeKey(int num)

Returns the pre-declared property name including properties names of the parent event type if any

Parameters:

num - index number of the property

Returns:

name

Throws:

NoSuchElementException - for invalid index

getNativeValue

public abstract Object getNativeValue(int num)

Returns the value of a pre-declared property including property values of the parent event type if any

Parameters:

num - index number of the property

Returns:

value

Throws:

NoSuchElementException - for invalid index

getNativeNum

public abstract int getNativeNum(String name)

Returns the index number of a a pre-declared property of the same name including property names of the parent event type if any

Parameters:

name - property name

Returns:

index starting at zero, ending at native-size minus 1; Returns -1 for non-existing property name

nativeContainsKey

public abstract boolean nativeContainsKey(Object key)

Returns the flag whether the key exists as a pre-declared property of the same name including property names of the parent event type if any

Parameters:

key - property name

Returns:

flag

nativeWrite

public abstract void nativeWrite(JsonWriter writer)
