Usage

build VelocyPack - Object

VPackBuilderbuilder =newVPackBuilder();builder.add(ValueType.OBJECT);// object startbuilder.add("foo","bar");// add field "foo" with value "bar"builder.close();// object endVPackSliceslice =builder.slice();// create slice

working with VPackSlice - Object

VPackSliceslice = ...intsize =slice.size();// number of fieldsVPackSlicefoo =slice.get("foo");// get field "foo"Stringvalue =foo.getAsString();// get value from "foo"// iterate over the fieldsfor (finalIterator<Entry<String,VPackSlice>>iterator =slice.objectIterator();iterator.hasNext();) {Entry<String,VPackSlice>field =iterator.next();    ...  }

build VelocyPack - Array

VPackBuilderbuilder =newVPackBuilder();builder.add(ValueType.ARRAY);// array startbuilder.add(1);// add value 1builder.add(2);// add value 2builder.add(3);// add value 3builder.close();// array endVPackSliceslice =builder.slice();// create slice

working with VPackSlice - Array

VPackSliceslice = ...intsize =slice.size();// number of values// iterate over valuesfor (inti =0;i <slice.size();i++) {VPackSlicevalue =slice.get(i);    ...  }// iterate over values with Iteratorfor (finalIterator<VPackSlice>iterator =slice.arrayIterator();iterator.hasNext();) {VPackSlicevalue =iterator.next();    ...  }

build VelocyPack - nested Objects

VPackBuilderbuilder =newVPackBuilder();builder.add(ValueType.OBJECT);// object startbuilder.add("foo",ValueType.OBJECT);// add object in field "foo"builder.add("bar",1);// add field "bar" with value 1 to object "foo"builder.close();// object "foo" endbuilder.close();// object endVPackSliceslice =builder.slice();// create slice
