public static class JsonDeserializationContext.Builder
extends Object

Builder for JsonDeserializationContext. To override default settings globally, you can extend this class, modify the default settings inside the constructor and tell the compiler to use your builder instead in your gwt.xml file :

 

 <replace-with class="your.package.YourBuilder">
   <when-type-assignable class="com.github.nmorel.gwtjackson.client.JsonDeserializationContext.Builder" />
 </replace-with>

Method Summary

Modifier and Type	Method and Description
JsonDeserializationContext.Builder	acceptSingleValueAsArray(boolean acceptSingleValueAsArray) Feature that determines whether it is acceptable to coerce non-array (in JSON) values to work with Java collection (arrays, java.util.Collection) types.
JsonDeserializationContext	build()
JsonDeserializationContext.Builder	failOnUnknownProperties(boolean failOnUnknownProperties) Determines whether encountering of unknown properties (ones that do not map to a property, and there is no "any setter" or handler that can handle it) should result in a failure (by throwing a JsonDeserializationException) or not.
JsonDeserializationContext.Builder	readUnknownEnumValuesAsNull(boolean readUnknownEnumValuesAsNull) Feature that determines whether gwt-jackson should return null for unknown enum values.
JsonDeserializationContext.Builder	unwrapRootValue(boolean unwrapRootValue) Feature to allow "unwrapping" root-level JSON value, to match setting of JsonSerializationContext.Builder.wrapRootValue(boolean) used for serialization.
JsonDeserializationContext.Builder	useBrowserTimezone(boolean useBrowserTimezone) Feature that specifies whether dates that doesn't contain timezone information are interpreted using the browser timezone or being relative to UTC (the default).
JsonDeserializationContext.Builder	useSafeEval(boolean useSafeEval) Feature that determines whether gwt-jackson should use JsonUtils.safeEval(String) or JsonUtils.unsafeEval(String) to deserialize JavaScriptObject JsonUtils.safeEval(String) is used by default.
JsonDeserializationContext.Builder	wrapExceptions(boolean wrapExceptions) Feature that determines whether gwt-jackson code should catch and wrap RuntimeExceptions (but never Errors!) to add additional information about location (within input) of problem or not.

Method Detail

failOnUnknownProperties

public JsonDeserializationContext.Builder failOnUnknownProperties(boolean failOnUnknownProperties)

Determines whether encountering of unknown properties (ones that do not map to a property, and there is no "any setter" or handler that can handle it) should result in a failure (by throwing a JsonDeserializationException) or not. This setting only takes effect after all other handling methods for unknown properties have been tried, and property remains unhandled.

Feature is enabled by default (meaning that a JsonDeserializationException will be thrown if an unknown property is encountered).

Parameters:

failOnUnknownProperties - true if should fail on unknown properties

Returns:

the builder

unwrapRootValue

public JsonDeserializationContext.Builder unwrapRootValue(boolean unwrapRootValue)

Feature to allow "unwrapping" root-level JSON value, to match setting of JsonSerializationContext.Builder.wrapRootValue(boolean) used for serialization. Will verify that the root JSON value is a JSON Object, and that it has a single property with expected root name. If not, a JsonDeserializationException is thrown; otherwise value of the wrapped property will be deserialized as if it was the root value.

Feature is disabled by default.

Parameters:

unwrapRootValue - true if should unwrapRootValue

Returns:

the builder

acceptSingleValueAsArray

public JsonDeserializationContext.Builder acceptSingleValueAsArray(boolean acceptSingleValueAsArray)

Feature that determines whether it is acceptable to coerce non-array (in JSON) values to work with Java collection (arrays, java.util.Collection) types. If enabled, collection deserializers will try to handle non-array values as if they had "implicit" surrounding JSON array. This feature is meant to be used for compatibility/interoperability reasons, to work with packages (such as XML-to-JSON converters) that leave out JSON array in cases where there is just a single element in array.

Feature is disabled by default.

Parameters:

acceptSingleValueAsArray - true if should acceptSingleValueAsArray

Returns:

the builder

wrapExceptions

public JsonDeserializationContext.Builder wrapExceptions(boolean wrapExceptions)

Feature that determines whether gwt-jackson code should catch and wrap RuntimeExceptions (but never Errors!) to add additional information about location (within input) of problem or not. If enabled, exceptions will be caught and re-thrown; this can be convenient both in that all exceptions will be checked and declared, and so there is more contextual information. However, sometimes calling application may just want "raw" unchecked exceptions passed as is.

Feature is enabled by default.

Parameters:

wrapExceptions - true if should wrapExceptions

Returns:

the builder

useSafeEval

public JsonDeserializationContext.Builder useSafeEval(boolean useSafeEval)

Feature that determines whether gwt-jackson should use JsonUtils.safeEval(String) or JsonUtils.unsafeEval(String) to deserialize JavaScriptObject

JsonUtils.safeEval(String) is used by default.

Parameters:

useSafeEval - true if should useSafeEval

Returns:

the builder

readUnknownEnumValuesAsNull

public JsonDeserializationContext.Builder readUnknownEnumValuesAsNull(boolean readUnknownEnumValuesAsNull)

Feature that determines whether gwt-jackson should return null for unknown enum values. Default is false which will throw IllegalArgumentException when unknown enum value is found.

Parameters:

readUnknownEnumValuesAsNull - true if should readUnknownEnumValuesAsNull

Returns:

the builder

useBrowserTimezone

public JsonDeserializationContext.Builder useBrowserTimezone(boolean useBrowserTimezone)

Feature that specifies whether dates that doesn't contain timezone information are interpreted using the browser timezone or being relative to UTC (the default).

Parameters:

useBrowserTimezone - true if should use browser timezone

Returns:

the builder

build

public final JsonDeserializationContext build()
