                                            String fieldName)

Produces DateTime from given node and field name

Parameters:

node - JsonNode

fieldName - Field Name

Returns:

LocalDateTime

checkError

public static final void checkError(com.fasterxml.jackson.databind.JsonNode root)

Checks if the JSON is error and throws exception if error found.

Parameters:

root - JsonNode

isEmptyJson

public static final boolean isEmptyJson(String json)

Returns true if the json is empty.

Parameters:

json - JSON string to check

Returns:

true if JSON string is "emptry"

toBD

public static final BigDecimal toBD(com.fasterxml.jackson.databind.JsonNode node,
                                    String fieldName)

Returns the BigDecimal for the fieldName. Not Required so returns null if field is not found.

Parameters:

node - JSON Node

fieldName - JSON field name to process

Returns:

BigDecimal value for fieldName

toBDrequired

public static final BigDecimal toBDrequired(com.fasterxml.jackson.databind.JsonNode node,
                                            String fieldName)

Parameters:

node - JSON Node

fieldName - JSON field name to process

Returns:

BigDecimal value for fieldName

toBD

public static final BigDecimal toBD(String value)

Converts the String to BigDecimal.

Parameters:

value - String to convert

Returns:

BigDecimal value

fixString

public static final String fixString(String inputStr)

Strips blank spaces at beginning and end of string. Also returns null if string is empty.

Parameters:

inputStr - String to fix

Returns:

Fixed String
