Method Details

isNull

public static boolean isNull(com.fasterxml.jackson.databind.JsonNode j)

getStringMember

public static Optional<String> getStringMember(com.fasterxml.jackson.databind.JsonNode obj,
 String memberName)

getNonEmptyStringMember

public static Optional<String> getNonEmptyStringMember(com.fasterxml.jackson.databind.JsonNode obj,
 String memberName)

getStringDefault

public static String getStringDefault(com.fasterxml.jackson.databind.JsonNode obj,
 String memberName,
 String def)

getIntMember

public static Optional<Integer> getIntMember(com.fasterxml.jackson.databind.JsonNode obj,
 String memberName)

getNumberMember

public static Optional<BigDecimal> getNumberMember(com.fasterxml.jackson.databind.JsonNode obj,
 String memberName)

getBoolMember

public static Optional<Boolean> getBoolMember(com.fasterxml.jackson.databind.JsonNode obj,
 String memberName)

getMemberList

public static List<String> getMemberList(com.fasterxml.jackson.databind.JsonNode obj,
 String memberName)

unwrapDAList

public static Optional<com.fasterxml.jackson.databind.JsonNode> unwrapDAList(com.fasterxml.jackson.databind.JsonNode obj)

Returns the JsonNode where `.isArray()` is true.

For DAList objects, Docassemble puts the actual JSON array nested in the `elements` attribute. This function lets you treat a normal JSON array and a DAList JSON object the same.

unwrapDADict

public static Optional<com.fasterxml.jackson.databind.JsonNode> unwrapDADict(com.fasterxml.jackson.databind.JsonNode obj)
